Here is a better example: http://groups.yahoo.com/group/boost/files/shifted_ptr/virtualtemplate.cpp Ouputs (compiled with gcc 3.0.4): Normal calls: void A::foo() [with U = int] void B::bar() [with U = int] Virtual calls: void A::foo() [with U = int] void B::bar() [with U = int] Philippe _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
